Message Passing Interface (MPI)

  • MPI is the standard of programming parallel applications using message passing.
  • Processes run on network distributed hosts and communicate by exchanging messages.
  • A community of communicating processes is called a Communicator. The default communicator is called MPI_COMM_WORLD.
  • Inside a communicator, each process is attributed a "process ID", called rank.
